WARNING: TrueCrypt is not secure as it may contain unfixed security issues

The development of TrueCrypt was ended in 5/2014 after Microsoft
terminated support of Windows XP. Windows 8/7/Vista and later offer
integrated support for encrypted disks and virtual disk images.
Such integrated support is also available on other platforms.
You should migrate any data encrypted by TrueCrypt to encrypted disks
or virtual disk images supported on your platform.
